The video discusses "illegal" LEGO building techniques that, while not actually against the law, are unconventional and can potentially damage the pieces. These techniques include:
1. Using a technic pin to connect two bricks in a way that puts stress on the pieces.
2. Building with a joystick piece in a way that causes stress on the piece.
3. Using a plate to connect two pieces in a way that puts pressure on the pieces.
4. Building with transparent pieces in a way that can cause a hazardous chemical bond.
5. Forcing a plate into a technic brick, which can micro-stress the pieces.
6. Building a circular link using trans orange studs and one by two plates, which can put pressure on the pieces.
The video also shows examples of custom LEGO builds created using these techniques, including a painful-looking lego concoction and a Doctor Strange portal ring. The creator also experiments with rapid-fire illegal techniques, including a technique that involves squeezing round studs in between the studs of a plate.
The video ends with the creator stepping on a "torture brick" they built earlier, which surprisingly doesn't hurt as much as they thought.
Here are the key facts extracted from the text:
1. Certain Lego connections are considered "illegal" because they put too much pressure on the pieces, leading to permanent damage, or are too fragile, causing the build to collapse.
2. Lego traditionally does not use these "illegal" techniques in their sets.
3. Avid Lego builders may experiment with these techniques to create unique designs.
4. One "illegal" technique involves attaching a technic pin to the inverted stud on the back of a brick and placing the back of another brick on the other side.
5. This technique can cause stress on the pin and make the connection insecure.
6. Another "illegal" technique involves using a joystick piece without the stem and attaching a glass pane to the head of the joystick.
7. This technique can put pressure on the joystick head and cause stress on the pieces.
8. A third "illegal" technique involves shoving a plate inside a panel to create a unique connection.
9. This technique can put pressure on the pieces and cause stress on the build.
10. Lego builders are split on whether certain techniques, such as using two plates perpendicular to each other, are "illegal" or not.
11. Using transparent pieces with other transparent pieces is considered "illegal" due to the potential for hazardous chemical bonds.
12. Forcing a brick into a certain shape can put pressure on the pieces and is considered an "illegal" technique.
13. Attaching a plate to the side of a technic brick is considered an "illegal" technique because it can cause micro-stresses on the pieces.
14. Curving a circular link to form a circle can put pressure on the pieces and is considered an "illegal" technique.
